This opportunity is for the acquisition of a specific part (NSN 7R-1650-016508978-CB, QTY 19 EA) that requires engineering source approval from the design control activity, as the item is flight critical and only previously approved sources have been solicited. Delivery is FOB Origin, and the Government intends to solicit and negotiate with only one source under FAR 6.302-1. To be considered, non-approved sources must submit all data required by the NAVSUP WSS Source Approval Brochure with their proposal, as failure to do so will result in disqualification. Proposals from all responsible sources will be considered if received within 45 days of the synopsis publication, though the Government retains discretion not to compete. No budget amount or specific performance location is specified in the description.
